Anatomy of a plant

5. - a thin, flexible barrier around a cell; regulates what enters and leaves the cell.
6. -An organelle with a double membrane in the cytoplasm of many eukaryotes. It may be concerned with photosynthesis, contain yellow or orange pigment, or contain starch.
8. - is the general term for the study of the internal structure of plants.
9. - a lipid consisting of a glycerol bound to two fatty acids, a phosphate group, and make up the cell membrane.
10. - Membrane-bound organelle found within a plant cell that is filled with water. This organelle takes up much of the space inside a cell and helps maintain its shape and size.
12. - powerhouse of the cell and produces ATP.
13. seedling.
15. - the largest structure in the nucleus of eukaryotic cells. Where the ribosomal RNA is formed.
16. - a tiny structure that carries out a specific structure within the cell.

1. - the first organ to appear when a seed germinates. It grows downward into the soil, anchoring.
2. - a cell organelle that helps make and package materials to be transported out of the cell.
3. - Dense fluid found between the stacks of thylakoid disks of a plant cell's chloroplast. It is where carbohydrate forming reactions occur during photosynthesis.
4. - proteins that speed up chemical reactions inside of plant cells.
7. -a threadlike body in the cell nucleus that carries the genes in a linear order.
11. - the membrane hub where most of the respiratory complexes occur and energy production in the form of adenosine triphosphate (ATP) is produced.
14. -A tube-like series of vessel elements with open ends. The walls that join the members have perforations or holes in them to allow water to pass through freely.
