Plants
List 5 characteristics of plants
They are multicellular organisms.
Cell type: Eukaryotes
They have a two-stage life Cycle.
They have walls and vacuoles.
They make their own Food
Explain 1 process plants perform
The process in which plants and other organisms convert solar energy into chemical energy is called PHOTOSYNTHESIS.
List 3 examples of plant organs
Roots, stems and leaves are the major kinds of organs in vascular plants
True or false.
Non vascular plants and some vascular plants are seedless.
TRUE
They spread, like all plants, by producing SPORES.
Pollen is made in the anther.
Explain Sporophyte stage
Plants make spores that are genetically identical to the parent plant.
What is the Chloroplast`s Function?
photosynthesis :chloroplast.
Chloroplasts have a green pigment called chlorophyll that captures energy from sunlight , and uses solar energy along with co2 and water to make food in the form of a sugar called GLUCOSE
Tiny openings located in leaves, that allows gas exchange.,
Give 3 examples of a Vascular seedless plant
Ferns
Whisk Fern
Horse Tails
State the characteristics of angiosperms
Vascular plants that produce flowers and fruits which surround and protect seeds.
Are the most abundant type of plant alive today. At least 260,000 living species of angiosperms are known and species are still being discovered.
Can be found in almost every ecosystem.
Explain gametophyte stage
In this stage plants produce gametes.
Female gametophytes produce eggs.
Male gametophytes produce sperm.
What are the two main groups of plants?
Vascular
Non vascular
in the plants , most of Photosynthesis process is performed in ...
1. Which are the 2 types of seed plants ?
2.Are seed plants vascular plants?
1. angiosperms and gymnosperms
2. Yes they are vascular
What does the pistil represents in flowers?
A pistil is the female reproductive structure in a flower. The seed develops within the ovary at the base of the pistil
For a new plant to be produce, a sperm cell must fuse with, or fertilize an egg cell. (sexual reproduction).
What is the difference between vascular an non vascular plants
A vascular system is a tube-like tissues that transport water, nutrients and other materials from one part of an organism to another part.
Non vascular plants dont have a vascular system. they use diffusion as the mechanism
Provide support and they transport water and minerals from the roots up to the leaves, This statements corresponds to..
Steam
Define SEED
A seed is a plant embryo and nutrients enclosed in a protective coating.
What does flowers represent in plants?
List all the most flowers have
Flowers are the reproductive structures of angiosperms.
Flowers are typically made up of sepals, petals, statements and a pistil.
Which are the 2 life cycles in which plants reproduce and disperse into new areas?
Sporophyte stage
Gametophyte stage
List and Explain the main parts of vascular plants
The root system: made up of roots and other underground structures.
The shoot system: made up of stems, leaves and flowers
State location and function of Roots in plants.
They supply plants with water and minerals from the soil.
Roots also anchor plants in the soil and can store extra food made through photosynthesis.
Usually below the ground
Are plants that produce seeds that are NOT enclosed in a fruit, This statement corresponds to
Give 3 examples
Gymnosperms
Cycads , ginkgoes and conifers.
What does the fruit represents and appears in plants=
As the seed develops (after the flower has been fertilized), the ovary matures into a fruit which covers the seed.
