What are cell walls made of? |
Cellulose and hemicellulose |
|
|
Why is it beneficial that plant cells can't move? (2 Reasons) |
1. It gives them the strength to grow upward and out 2. Won't immediately collapse if not watered for a day or two |
|
|
Do plants have limited or unlimited growth? |
Unlimited growth |
|
|
Is the primary cell wall of a plant cell alive or dead? |
The primary plant cell wall is dead |
|
|
What are cells glued together with? |
Cells are glued together with pectin |
|
|
Define plasmodesmata |
Plasmodesmata are channels connecting cells together that allow materials to move between them |
|
|
What is the difference between a symplast and an apoplast? |
Symplasts are interconnected living cells, while apoplasts are interconnected dead spaces. |
|
|
What are the two types of angiosperms (that we learn of in this course)? |
Monocots and Eudicots |
|
|
What are the characteristics of monocots? |
1. One cotyledon 2. Veins in leaves run parallel 3. Vascular bundles are arranged complexly 4. Floral parts usually in multiples of three 5. Root system is fibrous |
|
|
What are the characteristics of eudicots? |
1. Two cotyledons 2. Veins in leaves run branched 3. Vascular bundles are arranged in rings 4. Floral parts usually in multiples of five 5. Taproot is usually present |
|
|
What are the three types of simple tissues? |
1. Parenchyma 2. Collenchyma 3. Sclerenchyma |
|
|
What are the characteristics of parenchyma tissue? |
1. Very common in plants 2. Alive at maturity 3. Thin primary cell wall 4. Isodiametric shape |
|
|
What are the functions of parenchyma tissue? |
1. Photosynthesis 2. Storage of reserves 3. Seed dispersal 4. Wound repair |
|
|
What is the specialized function of parenchyma and what is the subclass that does it? |
The aerenchyma tissues are responsible for the aeration of roots in water |
|
|
What are the characteristics of collenchyma? |
1. Common in few plant families 2. Alive at maturity 3. Thick primary cell wall 4. Elongated shape 5. Flexible and elastic |
|
|
What are the functions of the collenchyma? |
1. Flexible support 2. Does not restrain growth |
