Difference between monocot & Dicot seed |
Monocot has one cotyloden and dicot has 2 cotylodens |
|
|
What would you expect to be the outcome of the effect of gravity on corn seedlings to be |
-the roots would grow upwards, shoots would grow downwards -this is because of the tropism of gravitropism -even if upside down, the root would make a u-turn around the seed, and the shoot would make a u-turn around the seed as well -this is as gravitropism has a positive effect on roots, and a negative effect on shoots |
|
|
What is leaf cutting? |
-a leaf or part of a leaf is cut from a plant and placed in soil -Cells near the cut portion form undifferentated meristematic tissue, which develop into roots or shoots. -Shoot buds grow from the base of the leaf cutting |
|
|
Advantages of leaf cutting? |
-provides genetically identical plants -simple and productive way to grow plants faster than from a seed |
|
|
What is succession |
the gradual change overtime in the species that form a comunity |
|
|
what is primary succession? |
Succession in an area that has no plants, can occur by bombs, strip mining |
|
|
what is secondary succession? |
succession in an area that has been disturbed, can occur by a forest fire, ect |
|
|
How can nutrients affect the growth and differentiation of a plant? |
nutrients such as hydrogen are needed for the plant to grow, nitrogen is needed for the green color and lack of can cause cholorosis |
|
|
How can soil affect the growth and differentiation of a plant? |
-soil is a medium in which retains water and provides the root with air. soil in which is sandy does not retain water well, and dies out quickly. Soil with too much clay has not enough air pockets, and holds too much water, causing the plant to drown |
|
|
What is a blade? |
large flattened areas of the leaf |
|
|
What is a rhizome |
a modified stem that stores food |
|
|
what is a sclerenchyma |
provides support for mature plants |
|
|
what is a source? |
an area in which glucose is produced |
|
|
what is a vascular plant? |
includes tracheophytes and angiosperms |
|
|
What do guard cells control? |
Gas exchange |
|
|
what type of carbohydrate is used for transport in the phloem |
sucrose |
|
|
What type of hormone is gibberellins |
stimulatory |
|
|
where are you most likely to find meristemic cells in a plant |
in the root cap at the tip of a root |
|
What type of structure is this? Monocot or dicot? |
Monocots herbaceous stem |
|
What type of structure? Monocots or eudicot? |
Herbaceous eudicot stem |
|
Structure? Monocot or eudicot? |

|
|
What is grafting? |
A bud, portion of stem, or root is cut from one plant and joined to another by placing the vascular cambium tissue of the 2 pieces together |
|
|
Advantages or grafting? |
Can be used to merge characteristics, repair damaged trees |
|
|
What is stem cutting? |
A shoot tip is cut and placed in a growth medium, where it devolops roots |
|
|
Advantages to stem cutting |
Genetically identical copies, produces a new plant faster |
|
|
What is Root cutting? |
Cutting is placed vertically in the growth medium, with bottom end pointing downwards |
|
|
