Plant Study Guide

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
