Plants and plant functions.

4. defensive organ that encloses and protects the developing reproductive structures
5. a living thing) undergo natural development by increasing in size and changing physically; progress to maturity/become larger or greater over a period of time; increase
7. a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, typically growing in a permanent site, absorbing water and inorganic substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll
10. invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen.
11. protects the seeds and also helps to spread them
12. The pollen-producing part of a flower
14. green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring
15. to produce food for the plant by photosynthesis
19. captures pollen

1. process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
2. reproduction
3. absorbs water/anchors the plant
6. colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms
7. The ovule producing part of a flower
8. The part of the stamen where pollen is produced
9. develop into seeds upon fertilization
12. the upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles
13. acts as a buffer against pollen contamination/to assist the process of fertilization
16. protect and nourish the embryo or young plant
17. light from the sun
18. holds the plant up/supports the leaves
