Plant Study Guide
| Term | Definition |
|---|---|
| Ovule | A plant structure in seed plants that produces the female gametophyte; contains an egg cell |
| Stigma | the sticky tip of a pistil |
| Anther | pollen is produced in the anther, at the top of the stalklike filament |
| Stamen | the male reproductive part of a flower |
| Petal | A colorful leaf like structure of some flowers |
| Ovary | a flower structure that encloses and protects ovules and seeds as they develop |
| Style | A slender tube connects the the stigma to a hollow structure at the base of the flower |
| filament | the thin stalk of the stamen |
| pollination | the transfer of pollen from male reproductive structures to female reproductive structures in plants |
| fertilization | the joining of a sperm cell and an egg cell |
| chlorophyll | a green pigment found in the chloroplasts of plants, algae, and some bacteria |
| embryo | the young organism that develops from a zygote |
| Seed coat | the outer covering of a seed |
| cotyledon | a seed leaf; sometimes stores food |
| monocot | an angiosperm that has only one seed leaf |
| Dicot | an angiosperm that has two seed leaves |
| vascular tissue | the internal transporting tissue in some plants that is made up of tube like structures that help water, minerals and food move |
| xylem | the vascular tissue through which water and nutrients move in some plants |
| Phloem | the vascular tissue through which food moves in some plants |
| tropism | the growth response of a plant toward or away from a stimulus |
| Pistil | the female reproductive parts of a flower |
| Characteristics of a seed plant | vascular tissue and they use pollen and seeds to reproduce |
| functions of plant's flowers and roots | roots have three main functions: 1)Anchor a plant in the ground 2)Absorb water and minerals 3)store food |
| How seeds are dispersed | by animals, wind and/or water |
| What is required for photosynthesis and what is produced? | sunlight, water and CO2. Oxygen, sugar, and plant food are produced. |
| What role chlorophyll plays in photosynthesis | |
| How plants reproduce through pollination and fertilization | |
| the differences between monocots and dicots (table from notes) | Monocots: 1)seed has 1 food storage area 2)straight leaf 3)petals in multiples of 3 Dicots: 1) 2 food storage areas 2) heart shaped leaf 3)petals in multiples of 4 or 5 |
| Thigmotropism | a plants response to touch |
| Phototropism | a plants response to light |
| Gravitropism | a plants response to gravity |
| Dormancy | a period when an organisms growth or activity stops |
| photosynthesis | the process by which plants use the suns energy to make their own food |
