All About Seeds
Mosses reproduce by spores and not seeds. True or False
True
Photosynthesis cannot take place without chlorophyll. True or False.
True.
Plants need chlorophyll to go through photosynthesis.
True or False
Deciduous trees do NOT lose their leaves
False.
Deciduous trees DO lose their leaves. Like Maple, Oak, and Sycamore trees.
These plants reproduce by spores on their fronds.
What are ferns?
Name the 2 types of root systems.
Fibrous and Taproot
Give the 2 names for the: Growth in width & Growth in length
Primary growth & Secondary Growth.
Primary- growth in length
Secondary- growth in width
Legumes are dry fruits that form a pod around the seeds. They have hard outer shells. True or False?
False
Legumes have a soft outershell.
The green substance in plant cells that is used to perform photosynthesis
What is chlorophyll?
True or False
Sepals might be confused with leaves
True.
The egg or unfertilized seed found in the ovary is called?
The ovule.
The tubes that carry nutrients, food, and water throughout the plant.
Xylem and phloem
Belief that life can come from nonlife
Spontaneous generation
This is when the seed will not germinate
What is Seed Dormancy?
Process by which sunlight, chlorophyll, carbon dioxide, and water are turned into sugar and oxygen.
What is photosynthesis?
True or False
Ephemeral plants grow slowly.
False.
Ephemerals grow very quickly. They go through their full life cycle in just 6 weeks.
The female part of the flower that produces ovules.
Pistil.
The shape of most monocot plants' leaves is...
long and thin like grass
Life can only come from life
Law of biogenesis
This is the breaking of the seed coat.
What is Scarification?
Diffusion through a membrane

True.
The male part of the flower that produces pollen
Stamen
Plants with red, yellow, and orange leaves have no chlorophyll.
True or False
False.
They DO have chlorophyll.
Response of plants to stimuli.....
Tropisms:
Geotropism: response to gravity (stems up/roots down)
Phototropism: Light (turn to the sun)
Chemotropism: chemicals (pollination of flowers)
This is a period of cold before germination.
What is Stratification?
Cell division for reproduction
What is meiosis?
True or False
Pomes have papery inner cores
True.
THE PROCESS BY WHICH POLLEN IS TRANSFERRED FROM ONE FLOWER TO ANOTHER TO CAUSE THE FERTILIZATION OF THE OVULE, THEREBY CREATING SEEDS
Pollination
Rootstock is important for grafting.
True or False
True
Tendrils of plants have negative tropism (move away)
True or False
False.
Tendrils move towards things to wrap around.
