Plant Reproduction Reproduction in seed plants

Gymnosperms Gymnosperm seeds are not enclosed

by a protective fruit

Gymnosperms1. What structure produces pollen?2. How is pollen transferred from the

male to the female cone?

Angiosperms Plants that produce flowers and fruits In your notebooks, list some

angiosperms you’re familiar with.

Angiosperms In gymnosperms, the cone is the

reproductive structure. In angiosperms, the flower is the

reproductive structure.

Angiosperms1. What is the function of flowers?2. What structures make up the male

parts of a flower?3. The female parts?4. What purpose do the color and

shape of the petals serve?

A Bee as a Pollinator On which of the bee’s structures can

you observe pollen?

All seed producing plants can be divided into 2 categories:

GYMNOSPERM Oldest type of seed plant Seeds are NOT enclosed

in a protective coating Needle-like leaves Produce cones for

reproduction Deep roots Mostly trees

ANGIOSPERM Most common type of

seed plant Seeds are protected

inside a fruit Produce flowers for

reproduction Live almost everywhere

on Earth

Pollination Angiosperms and gymnosperms are

wind pollinated but most angiosperms rely on birds, bats, and insects.

Seed Dispersal Seeds are dispersed by:1. Wind2. Water3. Animals

Seed dispersal Animals bury or hide fruits and seeds Animals eat fruits and seeds are not

damaged when they pass through digestive tract

Seed dispersalSeeds inside dry fruits that have tiny hooks attach to animals or clothing

Sketch and label a flower Sketch a flower in your notebook and

label the parts.

Gymnosperm vs. AngiospermWarm-Up

Create a Venn diagram in your notebook. Label the sections Angiosperm, Gymnosperm and Both. Classify each characteristic in the correct category.

____  Seeds protected inside a fruit ____ Reproduces using seeds____  Needle-like leaves ____  Produces cones for reproduction ____  Most common type of seed plant ____  Produces flowers for reproduction ____  Oldest type of seed plant ____ Contains leaves, stems, and roots____  "naked seed" ____  “seeds in a little case” angio (little case) ____ Redwood and pine trees ____ Apple trees and roses____ Uses photosynthesis to make food
