What are Plants?
All the following are true of plants except:
a. They have a cell wall
b. They have prokaryotic cells
c. They have a cuticle
d. They use photosynthesis to make their own food
b. They have prokaryotic cells
What do the roots do in plants?
Roots anchor the plant and take in water and nutrients.
What is the female part of a flower called?
the pistil.
When did the first ancestors of plants show up?
The late Ordovician Period
What is a cuticle?
A cuticle is a waxy layer that covers the parts of a plant that are exposed to air like leaves and stems.
1. Well developed root system
2. The production of seeds to reproduce
Are stems above or below the ground?
stems are mostly above the ground but some plants have stems that are below the ground.
What is the male part of a flower called?
Stamen
What is pollen?
Pollen are dust-like particles that produce sperms
What is a Vascular Plant?
Vascular plants have tissues made of cells that transport water and nutrients throughout the plant.
Why are some vascular plants tall while non-vascular are always short?
Some vascular plants are tall because of their well developed vascular tissues which transport water and minerals which helps them grow properly.
Non-vascular plants lack vascular tissues. This limits their growth.
What is the main function of leaves?
The main function of leaves is to use sunlight to make food during the process of photosynthesis.
What does a pistil contain?
Stigma, Style, Ovary, and Ovules
The body of a plant has 3 distinct regions known as _______, _______, and ________.
Roots, stems, and leaves!
What is a Xylem?
Xylem is a vascular tissue that carries water.
What are rhizoids? How are they similar and different than roots?
Rhizoids are root-like growths which extend beneath the body and anchor the plant.
Rhizoids are similar to roots because they both anchor the plant and act as a transport system. They are different because rhizoids lack vascular tissues.
What is the Palisade layer made up from?
The palisade layer is made up of elongated cells.
What happens after fertilization occurs in Reproduction?
Each ovule develops into a seed
How are vascular tissues arranged in a monocot stem and a dicot stem?
In a monocot stem, the vascular tissues are scattered throughout the stem, whereas in a dicot stem, they are arranged in a ring
What is a flower?
Flower is the reproductive organ of angiosperms.
List three reasons why seed plants are more common than non-vascular and vascular plants with no seeds
Three reasons why seed plants are more common than vascular or non-vascular plants without seeds:
a. They don't require water to reproduce
b. Their seeds are resistant to drying out
c. They have a well developed vascular system to transport water and nutrients
What are two things covered in a layer of epidermal cells?
Roots and Stems
In many grains, are the ovary walls thick or thin?
Thin
Name the function of each of the following parts: Stigma, Ovary, Ovule, Anther, Style.
Stigma: To attract and hold grains of pollen
Ovary: Contains one or more ovules
Ovules: Contains the egg cell inside the ovary
Anther: Produces grass of pollen
Style: Connects the stigma to the ovary
What is a stigma?
A stigma is a part of the flower that attracts and holds pollen.
