-Control the activity of the cell. It contains chromosomes which carry the genetic material or gene, it's the largest organellbe in the cell. Nearly all cells have a nucleus. It contains chromosomes

The cell wall is there for the protection of the cell and to keep it in shape. It also has to withstand pressure. Made up of cellulose. It gives the cell strength and rigidity.

It control what goes in and out of the cell. It forms a boundary between the cytoplasm of the cell and the outside

They carry out some of the reactions of respriration to release energy that the cell can use

Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protoctists such as algae. Animals do not have chloroplasts. Chloroplasts work to convert light energy of the sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplasts.

It is filled with a watery liquid called cell sap, a stored of dissolved sugars, minerals ions and other solutes

The living material Material somewhere between a solid and liquid into complex material. Where the activity takes place.

Enzymes are made of protein and amino acid.

Enzyme are very specific about which reaction they catalyze. only molecules with the exactly right shape will bind to the enzyme and react.

Is the movement of particles against a concentration gradient, using energy from repiration

Osmosis is the diffusion of water molecules. Osmosis is the movement of water molecule which is from a high concentration to a lower concentration. Osmosis can only happen if the membrane is permeable to water. We say that it is partially permeable membrane.

A group of tissues the perform a specific function

Any member of the kingdom plantea, comprimising multi seller organisms that typically produce they're own food from inorganic matter by the process of photosynthesis and that have more or less rigid cell walls containing cellulose.

_sasha is the most special person A living organism, like humans

. No photosynthesis

. Body is usually organized into a mycelium made from thread like structure called hyphae, which contain many nuclei

. Some single cell

. Cell wall made of chitin

. Feed by extra cellular secretion of digestive enzymes onto food material and absorption of the products

. Store carbohydrates as glycogen

'Dustbin kingdom'. They are mixed group of organisms that don't fit into the plants animals or fungi. Most protocits are microscopic single-called organism eg. Amoeba and Chlorella

. Microscopic

. Single called organisms; cell wall, cell membrane, cytoplasm and plasmid

. No nucleus

. Contain circular DNA some photosynthesis feed on dead matter 

the process of take oxygen from the air which is absorbed from lungs by inhalation and carbon dioxide will be move out by exhalation

Carbohydrates play a major role in our body as a "fuel" Digestion system breaks it into glucose and cells produce energy with glucose

Lipids contain the same three elements as carbohydrates- carbon, hydrogen and oxygen

Proteins are large biogical molecules, consisting of one or more long chains of amino acid residues 

Digestion is the process that the components of the food must first be broken down into their building blocks before they can be absorbed through the wall of the gut.

Waves of muscle contraction like this pass along the gut, pushing the food along, rather like squeezing toothpaste from a tube.

Plants use the carbon dioxide and water, in the presence of chlorophyll and light, to make glucose and oxygen. This process is called photosynthesis.

                                        light

carbon dioxide + water-----> glucose + oxygen                   chlorophyll

The chemical reactions that goes on in a cell which is controlled by a group of proteins.

Enzymes are biological catalysts.
