things plants need to grow
sun light, water , minerals, carbon dioxide and space
cells are in
stems and branches, trunks, and roots
cells form
flowers, fruit, vegetables and tissue
what do plants have in common with animals?
water, carbon dioxide, air, soil/dirt and water
non vascular plants
hornwort, liverwort and mosses
vascular plants
seedless (ferns, horsetails) and seeds (fig, tomato)
animal kingdom
move, walk, trot, jump , hop , spin, does not make own food
plant kingdome
makes food, cannot move, cell wall
fungus
yeast to bread, mushrooms to eat, mold to blue cheese, smuts, ruts, mildews,
animal cells
no cell walls, no chlorophyll
plant cells
minerals, chlorophyll, CO2, chloroplasts and need water
plant and animal cells
nucleus, cell membrane and vascular
animals
bones and blood
plants
cell walls and chlorophyll (use sun's energy to make food)
plants and animals
water and carbon dioxide
what is bacteria?
the tiniest little things that cause trouble
what is a protist?
they live in water and every cell is covered by a membrane
what is a fungus
they can cause problems to people and animals but they can also help us; can be one celled or many celled
what is kudzu
a vine that covers trees, houses and almost everything
what helps plants stay strong?
cell walls
vascular means:
composed of or containing vessels (like veins and arteries in your bodies)
xylem
tissue through which water, and minerals flow through the plant
cortex
a layer inside the epidermis of roots and stems. it stores food
epidermis
the outermost layer of a root, stem or a leaf
root cap
is a thing covering made up of cells, it protects the root tip as it grows into the soil
root hairs
threadlike parts of cells on the surface of a root
cambium
a layer of cells that separates the the xylem from the phloem
phloem
tissue through which food from the leaves moves down through a plant
transpiration
loss of water from a plant through its leaves
what do all plants have?
stem, leaves, buds, roots, root hairs, chlorophyll
roots
draw up water from the water and minerals from the soil and also stores food for plants
root plants (examples)
potatoes, beets, radishes, sweet potato, carrots, turnups and other plants you find in the grounds
taproot
one large root with a few hairy branching roots- grow deep into the ground and reach water deep down
fibrous roots
can make huge networks; spread out near the soil's surface; thin and hairy
aerial
roots that never touch the grounds ; plants like orchids ( take moisture from the air because their roots never touch the ground)
proproots
corn plants have them; look like fingers sticking out (they help prop up the plant) page 21
how are stems similar?
All stems support leaves 2. stems also hold the transportation system for plants (where water and minerals move from the roots to all parts of the plant)
simple leaves
Leaves with a single blade (maple and oak)
compound leaves
leaves that come in clusters (chesnut and locust)
outer layer of leaves
covered with a waxy coating called a cuticle. you can touch this layer
what does a leaf do for a plant?
making food for storage; regulate water loss; and helps support a plant
what makes orchid different?
some dangle in the air, some wrap around a tree branch, some green make food absorb the water and minerals- some roots are very flat and long
stomata
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
photosynthesis
food making process for plants; means putting together by light.
steps of photosynthesis
1. sunlight strikes a green part of the plant (like a leaf) 2. chlorophyll helps make the plant's food. chlorophyll is found in chloroplasts that act like tiny factories 3. inside them water and carbon dioxide from the air combine to make sugar and oxygen. The sugars help the leaf to make them go into the leaf's veins and off to parts of the plant 4. the oxygen the plant makes goes out into the air. all animals need this to breathe. animals breathe out carbon dioxide that help plants survive
respiration
the energy released when the sugars break apart
how do leaves change color?
when the temperature begins to drop, the leaves stop making chlorophyll. Yellow and orange appears... red later
where is the biggest variety of colors of leaves?
more north
