False
What are the male reproductive structures in flowers called?
Stamens
Fill in the blank: The female reproductive part of a flower is known as the __________.
Pistil
What process involves the transfer of pollen from anther to stigma?
Pollination
Which type of pollination occurs when pollen is transferred between flowers on the same plant?
Self-pollination
What is the term for the fusion of sperm and egg cells in plants?
Fertilization
True or False: All plants reproduce sexually.
False
What is the role of the ovule in plant reproduction?
It develops into a seed after fertilization.
Which part of the flower develops into fruit?
Ovary
What is the term for plants that can reproduce through vegetative propagation?
Asexual reproduction
What type of asexual reproduction involves the formation of new plants from runners?
Stolon formation
Fill in the blank: The process by which a seed develops into a new plant is called __________.
Germination
What is the main advantage of sexual reproduction in plants?
Increased genetic diversity
Which type of pollinator is most commonly associated with flowering plants?
Insects
What is a seed?
A fertilized ovule that contains an embryo and is capable of developing into a new plant.
True or False: All seeds require light to germinate.
False
What is the term for the protective outer covering of a seed?
Seed coat
What type of plants rely on wind for pollination?
Anemophilous plants
Fill in the blank: In flowering plants, the __________ is the site of pollen production.
Anther
What is cross-pollination?
The transfer of pollen from the anther of one flower to the stigma of another flower.
What is the function of nectar in flowers?
To attract pollinators.
True or False: Seeds can remain dormant for long periods before germinating.
True
What is a major disadvantage of asexual reproduction?
Lack of genetic diversity
What is the term for plants that can reproduce by seeds or vegetatively?
Perennials
What is pollinator syndrome?
The adaptation of flower traits to attract specific pollinators.
Fill in the blank: The __________ is the sticky part of the pistil that captures pollen.
Stigma
What type of plants produce seeds without flowers?
Gymnosperms
What is the role of the style in the flower?
It connects the stigma to the ovary.
True or False: Fruits develop from the petals of a flower.
False
What is the main purpose of fruit in plants?
To protect seeds and aid in their dispersal.
What does the term ‘angiosperm’ refer to?
Flowering plants that produce seeds enclosed within a fruit.
Fill in the blank: The part of the flower that attracts pollinators is often brightly colored and is called the __________.
Petal
What is the term for the process by which a seed disperses away from the parent plant?
Seed dispersal
True or False: All plants require pollination to reproduce.
False
What is apomixis?
A form of asexual reproduction in which seeds are produced without fertilization.
What environmental factors can influence seed germination?
Water, temperature, light, and oxygen.
Fill in the blank: The __________ is the part of the flower that produces ovules.
Ovary
What is the difference between a seed and a spore?
Seeds are multicellular and contain an embryo, while spores are unicellular and do not.
What is the primary function of roots in relation to plant reproduction?
Anchoring the plant and absorbing nutrients and water.
True or False: Some plants can reproduce both sexually and asexually.
True
