Ciliated cells are found mainly in the respiratory tract of the human body. Along the respiratory tract, mucus from mucus-secreting cells coat a layer.
Cilia are tiny hair like structures on the surface of the cell. The hairs sweep hair, mucus, trapped dust and bacteria up to the back of the throat where it can be swallowed.]]> 2020-05-22 05:26:18 UTC https://padlet.com/nisarparaansh/bbpxr3txkc8nohtw/wish/588350607 ROOT HAIR CELL-by Aarav nisarparaansh https://padlet.com/nisarparaansh/bbpxr3txkc8nohtw/wish/588350608 position- present just behind the root tip where they are continually being formed.function-Adapted for taking up water and mineral ions by having a large surface area/for more absorption. As root hair cells carry out photosynthesis they contain chloroplasts.
They are long and thin so they can penetrate between soil particles, and they have a large surface area for absorption of water through osmosis. Water passes from the soil water to the root hair cell's cytoplasm by mitosis.

Palisade cells are plant cells located on the leaves, right below the epidermis and cuticle. They are vertically elongated, a different shape from the spongy mesophyll cells beneath them. The chloroplasts in these cells absorb a major portion of the light energy used by the leaf.
Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. The palisade mesophyll consists of chloroplasts with chlorophyll that absorb the light energy.

The structure is given above. Consists of Dendrite, nucleus, Axon and cell body. Function is to transmit information in form of electrical impulses.
There are three main types of neurons. - Sensory neurons  -nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses. For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction.
Motor Neurons- neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands.
Interneurons - the central nodes of neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS). They play vital roles in reflexes.
Main Three types of Nervous Systems:
Central Nervous system (CNS) - Consists of the Brain and Spinal Cord.
Peripheral Nervous System (PNS) - Peripheral Nervous System - The PNS consists of the nerves and ganglia outside the brain and spinal cord.(ganglia - a structure containing a number of nerve cell bodies, typically linked by synapses, and often forming a swelling on a nerve fibre.)
Autonomous Nervous System (ANS) - Controls all the involuntary functions like the heart beat.

Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Checking the number of red blood cells in the blood is usually part of a complete blood cell (CBC) test. It may be used to look for conditions such as anemia, dehydration, malnutrition, and leukemia. Also called erythrocyte and RBC.
In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin; they can be viewed as sacks of hemoglobin, with a plasma membrane as the sack.

White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

Purpose:
Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.

How are they made?:
The bone marrow continuously produces white blood cells. They are stored within the blood and lymphatic systems until they are necessary for fighting an infection or disease in the body.

Types of white blood cells and their
Purpose: 
  • Lymphocytes: These are vital for producing antibodies that help the body to defend itself against bacteria, viruses, and other threats.
  • Neutrophils: These are powerful white blood cells that destroy bacteria and fungi.
  • Basophils: These alert the body to infections by secreting chemicals into the bloodstream, mostly to combat allergies.
  • Eosinophils: These are responsible for destroying parasites and cancer cells, and they are part of an allergic response
  • Monocytes: These are responsible for attacking and breaking down germs or bacteria that enter the body.
When necessary, monocytes travel to other organs, such as the spleen, liver, s, and bone marrow, where they transform into a cell called a macrophage.

Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia.

Position:
Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells.

Function:
The primary function of the sperm is to pass on the necessary biological information required to produce a new organism.

Structure:
A sperm cell consists of two parts, the head and the tail. The overall structure of the sperm makes it perfectly designed to carry out its function.

Adaptation:
The acrosome in the head contains enzymes so that a sperm can penetrate an egg. The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. The tail enables the sperm to swim. The cell membrane changes after fertilisation by a single sperm so that no more sperm can enter.

Fun Facts:
  • If a guy loses one testicle, the other is generally able to make enough sperm to create a baby.
  • It takes only one sperm cell to fertilize a woman's egg - but there's stiff competition for that honor. In fact, the average ejaculate contains 200 million sperm. Best of luck to each of you.
  • How long can a sperm cell live once inside a woman's body? About two days.

It's function is to join with the sperm cell. They also provide food for the new cell of the fetus.The egg is one of the biggest cell of the body.

The ovaries are two small organs, about the size of your thumb, that are located in the female pelvis. They are attached to the uterus, one on each side, near the opening of the fallopian tube.

The egg cell has the basic cell organelles such as mitochondria, lysosomes, two types of smooth endoplasmic reticulum (SER)-vesicular and tubular aggregates, multivesicular residual bodies, lipofuschin, microfilaments and microtubules. Golgi, RER and ribosomes are very rare. 

Fun Fact:
- The egg is all protein and it's not poisonous. If you can  get someone to provide you eggs and manage to put it on your tongue, you can eat out.

Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation 
  • Structure 
Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids.
  • function 
Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant via phloem.

Essentially, guard cells are two bean-shaped cells that surround a stoma. As epidermal cells, they play an important role in gaseous exchange in and out of plant leaves by regulating the opening and closing of pores known as a stoma.

Position:present roots to the plant


Structure:The guard cells are bean-shaped in surface view, while the epidermal cells are irregular in shape.

Function:Guard cells are specialized plant cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore.

Specialized Adaptions:They contain chloroplasts - Although they do not contain as many chloroplasts as mesophyll cells, guard cells have been shown be the only epidermal cells with chloroplast.

PRODUCED:guard cells are produced in pairs with a gap between them that forms a stomatal pore.]]> 2020-05-22 05:26:18 UTC https://padlet.com/nisarparaansh/bbpxr3txkc8nohtw/wish/588350617 RBCS nisarparaansh https://padlet.com/nisarparaansh/bbpxr3txkc8nohtw/wish/588350618 reserved by Gehena
A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. They typically live for about 120 days, and then they die. Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.
