Nearly all of the energy that drives an ecosystem comes from the sun in the form of solar energy. Solar energy enters the ecosystem through a process of photosynthesis that is the starting point for all forms of plant and animal life on the planet. The sun and solar energy are the beginning source of energy for almost all functioning ecosystems and organisms on the planet.
Answer: Examples of prokaryotes are bacteria and archaea.
Explanation:
Answer:
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
