Plant reproduction

  1. What is asexual reproduction?

A portion of one plant develops into a new and identical plant to its parent plant.

  1. What is sexual reproduction?

A plants sperm combines with egg to make 

  1. What is Alternation of Generations?

When the plants life cycleSwitched between diploid and haploid generations

  1. Define diploid

Full number of chromosomes

  1. Define haploid

Half number of chromosomes

Note: there will not be any questions about seedless plants on the quiz :) Thanks because i would be cooked if there was

  1. What are pollen grains?

They form a male reproductive tissue

  1. What do pollen grains produce?

Sperm cells

  1. How are pollen grains carried to the female reproductive structure? (the slides give several ways)

Wind, animals, gravity, water

  1. What are ovules?

Where the haploid egg develops

  1. What does the ovule produce?

embryo

  1. What is a zygote?

A fertilized embryo

  1. What is an embryo?

Immature diploid plant

  1. What is a seed?

Food supply

  1. What is the reproductive structure of gymnosperms?

Cones

  1. Seeds are part of which cone (male or female)?

Female


  1. Pollen is part of which cone (male or female)?

Male

  1. What is the reproductive organ of angiosperms?

Stamen

  1. What is the male reproductive structure of a flower?

Stamen

  1. What are the two parts of the male structure?

Stamen and anther

  1. What do each of the parts do?

They help with reproduction

  1. What is the female reproductive structure of a flower?

Pistil

  1. What are the three parts of the female structure?

Stigma, style, and ovary

  1. What do each of the parts do?

Stigma: Top of the pistil where pollen lands

Style: The tube under the stigma

Ovary: Base of the style

  1. Be able to label the parts of a flower (see the diagram from our gizmos activity worksheet)

Ok

  1. What is pollination?

The process of pollen traveling to the sticky stigma

  1. What is fertilization?

When pollen enters the ovule

  1. What happens to the fertilized egg after fertilization?

It becomes a seed

  1. What sometimes is produced from angiosperms that contains the seeds?

Fruits

  1. List 3 examples of fruits.

Strawberry, banana, and tomato

  1. How do fruits help with seed dispersal?

Animals can spread the seeds
