Answer:
Biodiversity is the different types of living organism found in this earth. The biodiversity is getting extinct due to the natural and human calamity.
Habitat loss and fragmentation: The excessive loss of trees due to urbanization and deforestation, species has lost their habitat and become extinct.
Over-exploitation: The over-exploitation of the natural resources has directly result in the biodiversity loss of plants and animals.
Pollution: The different types of air pollution, water pollution and noise pollution has damaged the large number of organisms on earth.
Invasive species: The introduction of alien species in the environment can cause the deterioration of the original species inhabiting in the environment.
Answer:
1) Plant cells have large sized vacoles than animal cells.
2) Plant cells have plastids and animal cell do not.
3) Plant cells have chloroplasts and animal cell don't.
4) Plant cells have cell walls and animals cells don't.
Explanation:
When you think about the main purpose of mitochondira (to produce energy; an easy idea how to remember the function of mitochondria in our bodies is to imagine them as energy factories or power plants) it becomes easy to understand why.
Animals (including us) move a lot more compared to plants. For movement you need energy and energy needs to be produced in our bodies in order for us to be able to move. Therefore, we have mitochondria that are bigger. Not only that, animal cells usually also have more mitochondria. All of this is probably done to keep up with the increased energy demands that moving organisms have.
Answer:
Cellulose is a type of carbohydrate polymer is used for structural support in the cell wall within plants
Explanation:
Cellulose, for example, is a major component of plant cell walls, which are rigid structures that enclose the cells (and help make lettuce and other veggies crunchy). Wood and paper are mostly made of cellulose, and cellulose itself is made up of unbranched chains of glucose monomers linked by 1 4 glycosidic bonds

Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
