Plant Introduction

SWBAT identify the 4 characteristics all plants have in common.

Plant Introduction

Plants Multicellular organisms

Eukaryotes (nucleus)

Autotrophs (make their own food)▪ Sunlight - the energy for

photosynthesis

Adaptations for Living on Land

For plants to survive onDry land, they must:

have ways to obtain water and other nutrients from their surroundings

retain water transport materials in their

bodies support their bodies reproduce

Retaining Water

Plants get water by absorbing it through the roots in the soil

Once water is inside a plant, there is a waxy, waterproof layer on the leaves called the

cuticle that helps prevent water loss

Transporting Materials

Plants need to move water and minerals from the roots to the rest of the plant andenergy from the leaves to theroots – larger plants need vascular tissues

Vascular tissue – a system of tube like structures inside a plant through which water, minerals, and food move.

Reproduction

Sexual Reproduction A sperm cell and an

egg cell join forming a fertilized egg called a zygote

Classifying Plants – Vascular vs. Nonvascular

Nonvascular Plants – plants that lack a well developed system of tubes for transporting water and other materials.

These are low growing and do not have roots for absorbing water from the ground, they get it from their surroundings.

They live in damp, shady places where they can get water easily.

Classifying Plants – Vascular vs. Nonvascular

Vascular Plants – Plants with true vascular tissue

Better suited to life in dry areas than nonvascular

The vascular tissue provides strength, stability and support They can grow quite tall like a

Redwood Trees
