True or False: Gymnosperms are usually large caducifolius trees and the seed is in a cone.
True: Gymnosperms are usually large caducifolius trees and the seed is in a cone.
100
The stem transports what substance through the conducting vessels?
The stem transport substances (sap) through the conducting vessels.
100
What 2 things do roots absorb and through what?
BONUS 200: What does the stomata of the leaves do?
Roots absorb water and dissolved mineral salts (raw sap) through the root hairs.
BONUS: The stomata of the leaves absorb carbon dioxide (CO2).
100
What are stolons? Give an example.
Stolons are stems that grow parallel to the ground and can develop roots to form another plant (strawberry plant).
100
How do ferns, mosses and liverworts reproduce? BONUS 200: What is the difference between the reproduction of ferns VS mosses and liverwort?
Mosses and liverworts reproduce by spores produced in the capsules located at the end of the cauloid.
Ferns reproduce by spores produced by sporangia, very small spore-producing structures that group together to form the sori.
200
Which classification of plants has the seed inside a fruit and a large variety of species?
Angiosperms have the seed inside a fruit and a large variety of species.
200
Which plant organ has the description as, "main body of the plant formed by nodes and internodes"?
The stem is the main body of the plant formed by nodes and internodes.
200
What is the difference between positive growth and negative growth? Does it occur in Tropisms or Nastic Movements?
Positive growth is growth towards the stimulus. Negative growth is growth away from the stimulus. It occurs in Tropisms.
200
What are tubers? Give an example.
Tubers are underground stems that store nutrients and can become a new plant (potato).
200
How does the pollination process occur? Give 3 examples.
The pollination process occurs thanks to the wind, animals (insects and birds) or water.
300
Name the two classifications of plants and the types of each classifications.
Non-Flowering plants: Moss and Liverworts, Ferns
Flowering plants (Spermatophytes): Gymnosperms and Angiosperms
300
Describe leaves and what are they formed by?
Leaves are flat and green structures formed by the petiole and the blade.
300
How does raw sap travel up the plant?
BONUS 200: how is the elaborated sap distributed?
Raw sap travels up the plant through the xylem vessels, from the roots through the stem to the leaves.
BONUS: The elaborated sap with nutrients is distributed by the phloem vessels from the leaves to the rest of the plane.
300
What are bulbs? Give 2 examples.
Bulbs are underground stems with thick leaves that store nutrients and can become a new plant (onions, garlic, tulips).
300
What is germination?
Germination is when a new plant is produced by the seed when it reaches the ground and the conditions are good.
400
What are 3 characteristics of Moss and Liverworts? BONUS 200: Name all 5 characteristics
Small and simple, No conducting tissues, All the cells absorb nutrients, Humid Environments, Rhizoids + Phyllodes + Cauloids
400
Name 2 vegetables that use its roots to store food reserves? BONUS 200: What vegetable uses its stem to store food reserves?
Carrots and beets
BONUS: potatoes
400
What is the difference between Tropisms and Nastic Movements?
Tropisms: permanent changes (by growing) that can be positive (towards the stimulus) or negative (away from the stimulus)
Nastic Movements: temporary changes. The plant can go back to its original position.
400
What are rhizomes? Give an example.
Rhizomes are underground stems able to create new plantas; they don't store nutrients (poplars, bamboo).
400
What is fertilization? How does this form seeds and fruit?
Fertilization is the pollen grain traveling down the style to the ovary and unites with the ovule. The ovule fertilized by the pollen grain becomes the seed. The ovary becomes the fruit that protects the seed.
500
What are the 5 characteristics of Ferns?
They have conducting tissues, More complex and larger, The leaves are called Fronds, The Rhizome (stem) develops underground, True roots, stems and leaves
500
Name 3 plant organs and 1 function of each plant organ.
Roots: Absorb water & mineral salts from the soil, Store food reserves (carrot, beet...), Anchor the plant to the ground.
Stem: Keep the plant vertical to support it, Transport substances (sap) through the conducting vessels, Store food reserves.
Leaves: Photosynthesis, Gas exchange
500
Describe photosynthesis. (Use: chloroplasts, elaborated sap and oxygen in your answer)
Photosynthesis takes place in the chloroplasts of the leaves with the energy of light, consuming the water and the CO2 to produce nutrients (elaborated sap) and oxygen.
500
Fill in the blanks: Asexual reproduction involves only one _________ and the offspring is ___________ to do it.
Asexual reproduction involves only one parent and the offspring is identical to do it.
