Osmosis is a form of transport that does not need energy

It would be a form of passive transport. Active transport does require energy-CF

Question

Fungi is a living thing, it does not have there own energy as they get it from other organisms.
Active - Low to high concentration need ATP. Passive - High to low concentration no need of energy.

Photosynthesis is why plants are green

The chloroplast in a plant cell is what converts sunlight into ATOP energy is green, which means the leaves of a tree do the heavy lifting when it comes to photosynthesis, like a thousand little mouths. The pigment in a chloroplast that absorbs red and blue light and reflects green is called chlorophyll.

Living things need to reproduce. Do some research on a living thing it can be anything from E.coli bacteria to a python. How does it reproduce?

Japanese Maple Trees, can reproduce through both sexual and asexual methods.

Sexual reproduction involves pollination of flowers, fertilization, and seed production. These trees produce two seeds encased in a helicopter like structure called a samara that aids in dispersal. Sexual reproduction increases genetic diversity.

Asexual reproduction happens through root sprouting or cloning. This reproduction method is common and efficient at producing new individuals. The offspring from asexual reproduction will be genetically identical to the parent tree. Though this method is efficient a genetically identical population of any living thing can be more vulnerable to diseases and environmental changes and the consequence could be the entire population is wiped out.

Octopi mate sexually, mashing their face bits together, what's interesting is the amount of care and self sacrifice the mothers go though after the deed. They wait with her clutch of eggs and starve for the entire 6-10 months they spend in egg, all while the father wonders off and potentially mates a few more times before crooking himself. for such an overtly intelligent being to just waste away like that makes you a little sad, in stark contrast crabs (which are a fair bit more stupide) wont even wait to find a meal, the mothers just eat their babies immediately after making them.

cannabis

growers grow female plants separately from male plants to increase the production of resin, the buds of females plants contain the highest concentrates of thc, cannabis products includes flowers/fruit.resin.hashesh I hate writing some I have keep on going back n forth here

Polar bears mate sexually, they use their scent of smell to track potential partners and follow them for many miles, often to tempt heard them away from other males. Once Once the egg is fertilized it wont immediately enter the uterus until the fall, which give the bear time to build up fat for the pregnancy, females can mate with many different males within a year, if their eggs fertilize it can result to giving off springs to different fathers at the same time. They will dig a den and live in until they give birth and the cubs are grown and ready to leave. During this time they enter a hibernation like state where they will not eat, drink, urinate, poop until they leave. As they enter the den in the fall they will hibernate up until 60 days later in November-January they will give birth to 1-3 cubs which will be about 30cm long and weigh 500g, cubs cannot keep warm themselves so they remain in the den for serval months, in the spring the cubs will come out of the den once they have learned to walk.

Komodo dragons can reproduce offspring asexually, in a process called "parthenogenesis." This form of reproduction is possible due to the females possessing both Z and W chromosomes.

Tardigrade or Water Bear

2025-01-17 18:42:55 UTC

Tardigrades are segmented micro-animals. There are several different species found throughout the planet in many different environments. They reproduce sexually, and lay eggs. They are known to be able to withstand harsh environments such as, extreme cold and heat, high and low pressure in mountains and beneath seas, and can even survive in the vacuum of space. Tardigrades are predatorial and consume Nematodes and other smaller organisms. There are around 1,500 species of Tardigrades, and the earliest known fossils are around 500 million years old. They grow to a length of 0.5 mm when fully grown.

The smallest unit of organization of a living things is the cell ,cells can proform allthe fuctiona we associate with life

All cells have a cell membrane, a region containing cytoplasm and DNA. As well as organ like parts, like the nucleus or mitochondria
