WHAT IS A PLANT?

PLANT ADAPTATIONS FOR LAND.

• They must have ways to obtain water.
• Retain water.
• Transport

MOSSES

• There are more than 10,000 species.
• Mosses are the most diverse group of Nonvascular plants.
• Mosses usually grow in sidewalk cracks and on tree trunks.

LIVERWORTS

• There are more than 8,000 species of liverworts.
• Liverworts are often found growing as a thick crust on rocks.
• Liverworts also usually grow on soil along the sides of a stream.

HORNWORTS

• There are fewer than 100 species of hornworts.
• Hornworts are seldom found on rocks and tree trunks.
• Hornworts usually live in moist soil often mixed with grass plants.

SEEDLESS VASCULAR PLANTS

• They share two characteristics:
• Ferns, Club mosses, and horsetails.
• They do most of the same things.

FERNS

• There are more than 12,000 species.
• Ferns have true vascular tissue stems.

HORSETAILS

• There are very few horsetails on Earth today.
• The stems of Horsetails are jointed.

CLUB MOSSES

• Club mosses have have true stems.

SEED PLANTS

• Plant that reproduces by means of seeds not spores.

VASCULAR TISSUE

• It is where water and nutrients are conducted.

POLLEN AND SEEDS

• Pollen fertilizes other female plants.
• Is what plants grow out of.

SEED STRUCTURE

SEED DISPERSAL

GERMINATION

ROOTS

• The part of the plant that attaches itself to the ground.
• It takes in water and nourishment to the plant, so the plant can grow.

STEMS

• The main body or stalk shrub.
• It typically raises above the ground but occasionally subterranean.

LEAVES

• A leaf is an organ of a vascular plant.
• A leaf is also the part of plant that is used for photosynthesis.

GYMNOSPERM

• A gymnosperm is a vascular plant that produces seeds.
• It is also not protected by fruit, which is a ripened ovary.

EXAMPLES OF GYMNOSPERMS

• They do not have any flowers on them.

ANGIOSPERMS

• Angiosperms are seed-bearing vascular plants.

EXAMPLES OF ANGIOSPERMS

• It is a plant that has flowers and produces seeds enclosed.

MONOCOT VS. DIOCOT

• Monocots are typically seeds that only have one cotyledon.
• Diocots typically have have two embryonic leaves or cotyledons.

PLANT TROPISMS: TOUCH, LIGHT, AND GRAVITY

• A tropism usually indicates growth and movement.
