PLANT

ADAPTATIONS

Plants have adapted to make their own food.

- Autotroph: organisms produce their own organic compounds by photosynthesis

Heterotrophs and Autotrophs

This beautiful leaf-shaped sea slug Elysia chlorotica lives in shallow pools along Atlantic coast of North America, eats algae with gusto - one meal is enough for its lifetime! - and by using photosynthesis like any other plant, shatters the most basic definition between the "animal" and "plant" kingdoms.

Animal, plant or both?

It only eats one meal of Algae and then it never has to eat another meal for the rest of its life! (Kinda reminds me of some alien species that alledgedly use photosynthesis to survive, and they are obviously plant animal hybrids too) Makes sense to me.    

What type of relationship is this?

What is the main plant organ that carries out photosynthesis??

Answer: The Leaf

How do gases enter and exit the cell?

Activity- Stomata Prac

Stomata

Stomata USUALLY on the undersurface of a leaf

Palisade mesophyll

Spongy mesophyll

Stoma with two guard cells

Upper Epidermis

Lower Epidermis

Plants that produce flowers are classified as Angiosperms.

These plants are all vascular plants. Have various types of flowers Live in a variety of diverse environmental

conditions. They can be further described as being

Hydrophytes, Mesophytes, Xerophytes or Halophytes.

Environmental adaptation in Angiosperms

Hydrophyte

Mesophyte

Xerophyte

Pits with sunken stomata

Halophyte
