Classifying Plants2.
Objectives● to understand the plant classification
● to understand the characteristics of ferns
● to differentiate between dicots and monocots
3.
Plants● multicellular organisms
● green (at least one part) because of chlorophyll
● chlorophyll absorb energy from sunlight for photosynthesis
● photosynthesis - making food by using sunlight and water

Ferns (папоротники)● Have leaves called fronds
● Do not have flowers
● Reproduce by spores produced on the underside of fronds

Spores for reproduction15.
16.
Flowering plants● Reproduce sexually by flowers and seeds
● Seeds are produced inside the ovary found inside the flower
● Can be divided into two groups – monocotyledons and dicotyledons

Seed found inside the ovary18.
19.
Monocotyledons● Cotyledon
● One leaf growing from the seed
● Flower
● Flowers from monocotyledons contain petals in multiples of 3
● Leaves
● Leaves from monocotyledons have parallel leaf veins
● Root
● Fibrous root system

One leaf growing from the seed- monocotyledon21.
22.
Dicotyledons● Cotyledon
● Two leaves growing from the seed
● Flowers
● Flowers from dicotyledons contain petals in multiples of 4 or 5
● Leaves
● Leaves from dicotyledons have reticulated leaf veins (web-like network)
● Root
● Tap root system
