The Flowering Plant

Leaves

carry out photosynthesis

Buds

are an undeveloped shoot (system)

Flowers

essential for plant reproduction

Roots

• anchor the plant,

• absorb water and minerals,

• transport absorbed materials to the shoot

• used to store food (in some plants)

Stem

• transports water and minerals from root to leaves and flower

• transports food made in leaves all around the plant

• supports aerial parts of the plant

• Leaves, flower, and fruit make food by photosynthesis

Shoot system

Is above the ground and system organs are the stem, the leaf, and the flower

Root system

is below ground and is made up of a single root organ

Stomata

are microscopic pores in the epidermis of leaves

Transpiration

the loss of water vapour from the aerial parts of plants, such as the leaves

Cohesion

is the force of attraction between water molecules

Adhesion

is the force of attraction between water molecules and other molecules

Dermal tissue

layer on the outside of the plant for protection

Ground tissue

middle layer that is involved in food storage and photosynthesis, while supporting and strengthening the structure of the plant

Vascular tissue

Made up of 2 channels; xylem and phloem

Xylem

transports water and minerals

Phloem

transports the products of photosynthesis (glucose-food)

Lignin

prevents xylem from collapsing inwards

Lenticles

opening in the stem of plant that allows gas exchange

Turgor Pressure

pressure against the cell wall caused by the cell membrane pushing against the cell wall, as it is full of water
