Plants Flashcards
Cell Membrane
A semi permeable barrier that lets good things in and bad things out of the cell
Cuticle
Outside layer of a leaf, is used for protection to keep the leaf from drying out
Cell wall
Thick protection for the cell, made with cellulose
Roots
Absorb nutrients for the plant, stop erosion, and store the plants nutrients
Angiosperm
Flowering plant that produces fruit to hold the seeds.
True or false, Angiosperm are found in almost every corner of the world?
True
Name two characteristics of plants
Make their own food using chlorophyll and photosynthesis
Have cell walls
Have a cuticle
What does vascular mean?
Have tissues that deliver needed materials throughout the whole plant
True or false, non-vascular plants have pipes to transport their water and nutrients
False
What is gymnosperm?
A non flowering plant
What is an example of a gymnosperm?
Pine trees
True or false, an example of an Angiosperm plant is a rose
True
True or false, an angiosperm plant has no flowers and no seeds
False
True or false, 70% of all plants are angiosperms
True
How do seedless plants reproduce?
By using spores or budding
Name three parts of a seed and why each one is important
Young plant-reproduction
Seed coat-protection
Stored food-energy for young plant
Why do Angiosperms have fruit?
To attract animals to eat them so there seeds will travel everywhere
Name two types of Angiosperms
Monocots-one seed leaf, vascular tissue scattered
Dicots-two seed leaves, vascular tissue in a ring
Define xylem
Transports water and minerals throughout the plant
Define Phleom
Transports sugar molecules
Name three functions of roots
Supply plant with water and minerals
Support and anchor plants
Store surplus food
Name three functions of stems
Supports the plants body
Transport materials btw roots and shoots
Store materials
Sepal
Small leaves that protect the bud
Petal
“showy” part of the flower. It’s designed to attract insects to allow polonation
Stigma
A sticky part of the pistil, it “captures” and holds pollen
Style
Holds the stigma high enough to allow pollen to land on the stigma
Ovary
Produces eggs. It swells to form a fruit after fertilizing accurs
Chlorophyll
Green pigment in plants. It is responsible for photosynthesis
Root hairs
Expander singe of the root in order to absorb more
Gymnosperm
Naked seed cone bearing coniferous
Pollen
Male sex cell for plants produced by the anther
Pollination
the act of pollen landing on the female part of the plant
Stamen
Male part of the flower that contains Anther and Filament. The Anther produces pollen, and the Filament supports the anther
Pistil
Female part of the flower, it contain stigma, style, and ovary
Anther
Produces pollen
Filament
Supports anther and raises it higher to allow an insect to get its pollen
Stomata
Small openings in the underside of a leaf that help get rid of wast from photosynthesis
Spore
A method of reproduction in simple plants like a fern
Cotyledon
Food source for seed, it gives energy to sprout
