Characteristics of Plants
* plants are multicellular
* they are eukaryotes
* membrane- bound organelle
Plants Life Cycle 1
Sporophyte- plants make spores that are genetically identical to the parent plant
Plants Life Cycle 2
Gametophyte- plants reproduce gametes
Female game-eggs/Male game-sperm
New Plant to Repro.
a sperm cell must fuse with, or fertilize an egg. The fertilized egg can grow into a sporophyte
* supports and protects the plant cell
* determines size and shape
the main component of plant wells and walls
plant contains the vacuole. If vacuole losses water, the plant begins to wilt.
the process the plants and other organisms use to convert solar energy to chemical energy / occurs in an organelle called chloroplast
green pigment that captures energy from sunlight
tube like tissues that transport water, nutrients, and other materials/ allows plants to grow large
water moves from the environment and throughout the plant by diffusion
have a vascular system
1} root system
2} shoot system
made of roots and other underground structures
above ground structures
ex. stems, leaves, flowers
3 main- Vascular Plants
nonvascular structure that help mosses attach to surfaces and help plants get water and nutrients
have roots and rhizomes that help them spread
underground stems from which new leaves and roots grow
a plant embryo enclosed in a protective coating
tiny structure in which sperm forms
plants that produce seeds that are not enclosed in a fruit
produce seeds in a large woody structure called cones that grow in a thick trunk
vascular plants that produce flowers and fruits that surround and protect seeds
cover and protect the flower while it is growing
male- repro. structure made up of an anther which produces pollen
female- pistil is the repro. structure seed which develops in the ovary at the base of the pistil
modern medicines are derived from chemicals found in the plants
