I was assigned a worksheet to work on from school, but out of the 20 questions i'm stuck on 4. Can anyone help me please?
Secondary growth:
A. results in the formation of wood.
B. increases plant height.
C. is especially common in monocots.
D. occurs in all dicots.
E. A and C
F. B and D
G. A and D
If an angiosperm plant has stems with vascular bundles in a scattered arrangment, you would expect it to have:
A. a root with xylem in a cross pattern and seeds with two cotyledons
B. a root with xylem arranged in a circle and seeds with two cotyledons
C. a root with xylem in a cross pattern and seeds with one cotyledon
D. a root with xylem arranged in a circle and seeds with one cotyledon
The xylem and phloem evolved once in the common ancestor of vascular plants and unites all the vascular plants. This makes it a:
A. synapomorphy for vascular plants and is an analogous characteristic
B. homoplasy for vascular plants and is an analogous characteristic
C. synapomorphy for vascular plants and is a homologous characteristic
D. homoplasy for vascular plants and is a homologous characteristic
If the concentration of a solute inside a cell is higher than the concentration of the solute outside the cell:
A. the cell is hypertonic to the outside and movement of more of the same solute into the cell would occur through diffusion
B. the cell is hypotonic to the outside and movement of more of the same solute into the cell would occur through diffusion
C. the cell is hypertonic to the outside and movement of more of the same solute into the cell would occur through active transport
D. the cell is hypotonic to the outside and movement of more of the same solute into the cell would occur through transport
