2.
There are _____ stages, or generations, in all plant life cycles.
3.
_________________ is a compound that is made in the leaves of plants.
4.
The two tissues in a plant’s vascular system are ________ and ________.
5.
Inside a leaf, the process of photosynthesis takes place in the ________________.
6.
Gases enter and leave the plant through tiny openings at the bottom of the leaf called
__________.
7.
All plants have four common characteristics, or traits, that define them as a plant.
1). All plants are _____________________.
2). All plants have a __________ inside each of their cells and a _____ _____ on the
outside of their cells.
3). All plants are _____________, which means they are a food source for other

C3.2
1. For the ancestors of the first plants, what were some advantages to living on land?
2. What are three physical adaptations that make mosses able to live on land?
3. What are two characteristics, you can observe without using a microscope, that
distinguish vascular plants from nonvascular plants?
4. Vascular plants such as ferns can grow bigger and taller than nonvascular plants
such as mosses. Does this mean they can also capture more sunlight? Explain
your response.

5. Consider the conditions that are needed for mosses and ferns to reproduce
sexually. Sexual reproduction increases genetic diversity within a group of plants,
while asexual reproduction does not. Explain why asexual reproduction is still
important for both moss and fern plants.
C3.3
“Seeds and pollen are reproductive adaptations.”
1). List, and describe, at least three ways seeds are different from spores?
2). Describe at least one way fertilization in seed plants differ from
fertilization in seedless plants?
3). Seed plants are found in environments where seedless plants are not. List
at least two reasons why.
4).What is the difference between a spore and a pollen grain? What is one
way spores and pollen grains are similar?
5). Gymnosperms produce a lot of pollen, and most of it blows away, never
fertilizing an egg. Why might this characteristic help a plant species survive?
C3.4
“Many plants reproduce with flowers and fruit.”
1). Which part of a flower becomes a fruit?
2). How are animals involved in life cycles of some flowering plants? (eating nectar,
pollinating, dispersing seeds, etc.)
3). What are three ways that humans depend upon plants?
4). If you observed three plants in a forest – a moss, a fern, and a flowering plant –
which do you think would have the most insects nearby and why?
