True or False: All plants are multicellular
True
Which organelle is found in plant cells but NOT in animal cells?
A) Nucleus,
B) Chloroplast,
C) Mitochondrion,
D) Cell membrane
B) Chloroplast
Chloroplasts: What is their primary job in a plant cell?.
Answer: To convert light energy into chemical energy (food) through photosynthesis
What is the name of the simple sugar plants produce during photosynthesis?.
Glucose
These plants, like mosses and liverworts, lack tubelike structures to move water.
Nonvascular plants
Plants are called consumers because they eat other organisms for food.
False (They are producers because they make their own food).
What is the waxy, protective layer on leaves and stems called? A) Cellulose, B) Vascular tissue, C) Cuticle, D) Stomata
C) Cuticle.
Vascular Tissue: What do these tubelike cells do for the plant?
They transport water and nutrients throughout the plant.
Most of the plants you see and eat, like grass or oak trees, belong to which broad group?
Seed plants.
What is the name for plants that produce seeds in a cone, such as a pine tree?.
Gymnosperms
Scientists hypothesize that land plants evolved from ancient green algae.
True
In the plant kingdom, phyla are replaced by which classification group?
A) Families,
B) Divisions,
C) Classes,
D) Orders.
B) Divisions.
Cell Wall: Why is this structure important for land plants?
It provides support and protection.
What are two common ways seeds are dispersed in the environment?.
Wind, water, or animals.
What is the name for plants that produce seeds in a fruit, such as a tulip or a magnolia?.
Angiosperms.
The cell wall of a plant is made of a rigid material called lignin only.
False (It is made of cellulose, though some plants also produce lignin for extra strength).
Which of these is a vascular plant that reproduces with spores?
A) Moss,
B) Pine Tree,
C) Fern,
D) Tulip
C) Fern.
Central Vacuole: What does this large organelle store?
It stores a watery liquid called sap
Because they provide food for all other organisms, plants are known as what in an ecosystem?.
Producers
If a plant is "seedless," what structure does it use to reproduce instead?.
Spores.
All plants produce flowers and seeds.
False (Seedless plants like mosses and ferns reproduce with spores).
Which substance makes cellulose even more rigid in woody plants?
A) Sap,
B) Lignin,
C) Glucose,
D) Chlorophyll
B) Lignin.
Cuticle: Aside from protection, what is its main function regarding water?.
To slow the evaporation of water from the plant's surface.
Why did the first land plants likely live only in moist areas?
Because they lacked adaptations for dry land and needed water for reproduction.
What are the two main "divisions" that seed plants are classified into?.
Gymnosperms and Angiosperms.
