Explanation: it also provides. Functions

Answer 2

The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.

What is cell membrane?

The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.

When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that  substance are moving their own concentration gradients.

Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.

D. transferring pollen from the ovule to the ovary
Please hurry and answer for me plz!

Answers

Bees, which are known for aiding in pollination, help with transferring pollen from the anther to the pistil. The correct option is C.

What is pollination?

Transferring pollen grains from a flower's male anther to its female stigma is the process of pollination.

Every living thing, including plants, strives to produce progeny for the following generation. Making seeds is one method through which plants can create progeny.

Bees are necessary for the growth of plants and flowers. They use the pollination process, in which they move microscopic pollen grains from one blossom of one sort of plant to another flower of the same kind.

The transfer of this pollen aids in the growth of the blooms which will ensures that a plant will produce full-bodied fruit and a full set of viable seeds.

Thus, the correct option is C.

What is the rise in biodiversity in woodland ecosystem?

In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.

Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.

Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.
