What is a plant?
True or false: the plant kingdom evolved from primative algae.
True.
True or false: mosses don’t have roots or leaves.
True
True or false: the process of turning inorganic matter into organic matter is called elimination.
False: it is called photosynthesis.
True or false: plant offspring are always genetically identical to their parent plant.
False. Flowers are a combination of both parents’ genetic material.
True or false: flowers can have both male and female reproductive organs.
True, hermaphrodite flowers exist. However, there are also unisexual flowers.
Define chloroplast.
Part of a plant cell that contains chlorophyll, where photosynthesis happens.
What is the difference between hepatica and mosses?
Hepatica don’t have conductive vessels, whereas mosses do.
What is cell respiration?
Cell respiration is what mitochondria do in order to provide energy for the plant cell.
What is asexual reproduction?
Reproduction that does not need gametes, the parent plant is identical to the offspring.
What is the name of the male organ of angiosperm flowers?
The stamen.
What kind of matter do plants use as energy?
Inorganic matter
What is the difference between gymnosperms and angiosperms?
Gymnosperms have cones that produce pollen and ovules, angiosperms have flowers that develop into fruit once fertilized.
What are the waste substances that result from plant nutrition?
CO2, O2, and water
What is the difference between tropism and nastic movement?
Tropisms are the growth responses of plants due to external stimuli. Nastic movements are temporary movements in one part of a plant; they are faster and reversible.
What is the difference between sporocytes and gametophytes?
Sporocytes reproduce asexually using spores, gametophytes reproduce sexually using gametes
What are the four tissue types that plants have?
Chlorophyll tissue; supporting tissue, protective tissue, conductive tissue
What is a bryophyte?
Non vascular plants that don’t have seeds, flowers, or well developed conducive vessels to transport sap
What is the first step of plant nutrition and where does it take place?
The first step is the absorption of water and minerals in the roots (specifically, the absorbent hairs on the roots)
Name two processes that are regulated by plant hormones.
Growth, leaf drop, and fruit ripening.
What are the two kinds of pollination?
Cross pollination: when pollen reaches the carpel of a flower of another plant (most common)
Self pollination: pollen reaches the carpel of a flower on the same plant.
What are the three plant organs and what is one function of each?
Roots: absorb nutrients and anchor plant
Stem: keep the plant straight and support flowers and buds
Leaves: gas exchange and photosynthesis
What are the three main functions of a root?
Absorb water and minerals, anchor the plant to the ground, and store reserves of nutrients
Name two out of the three reasons that photosynthesis is so important.
It creates organic material that becomes food for heterotrophs; it produces O2 which is essential for many things to breathe; it removes CO2 from the atmosphere which helps regulate the planet’s temperature
What is vegetative reproduction and what are two examples of it?
Vegetative reproduction is when a new plant grows from a part of the parent plant, can be a bulb, tuber, stolon, or rhizome
What are the six stages of reproduction in flowering plants?
Production of pollen
Pollination
Fertilization
Seed formation
Fruit formation
Germination
