Can somebody give me the answer for these

1.the smallest structural and functional unit of an organism

it was discovered by Robert Hooke

2. the unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

3 .Microscopes allow humans to see cells that are too tiny to see with the naked eye. Therefore, once they were invented, a whole new microscopic world emerged for people to discover

4. there are two basic kinds of cells: prokaryotic cells and eukaryotic cells.

prokaryotic cells :are simple cells that have no cell nucleus

eukaryotic cells:  are  complex cells with many organelles and other structures in the cell.

5.Plant cells have a cell wall in addition to their cell membranes while animal cells only have a surrounding membrane.

Both plant and animal cells have vacuoles but they are much larger in plants, and there is generally only 1 vacuole in plant cells while animal cells will have several, smaller ones.

6.PLASMA MEMBRANE/ CELL MEMBRANE

CYTOPLASM.

NUCLEUS.

7.Some substances pass through small holes in the surface cell membrane. This is called diffusion and does not require the cell to expend energy

hope it was helpful

Explanation:

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
