The part of a plant that is the stalk-like part of a leaf is the

Accepted Answer

The petiole is the part of the leaf which most closely resembles the stem from which the leaf came.Please see section 21.4 for more information.

Question 8

Roots are long and thin to make them good at absorbing.

Accepted Answer

Tubers are swollen underground stems specialized for storage.Please see section 21.4 for more information.

Question 13

Dicots have vascular bundles scattered throughout the ground tissue.

Accepted Answer

Dicots have their vascular bundles in a ring while monocots have themm scattered throughout the ground tissue.Please see section 21.4 for more information.

Question 14

You are given a sample to analyze and told that it comes from a plant growing actively in the summer,specifically from one tissue in the stem.Chemical analysis shows that it contains abundant sucrose.You would guess that the tissue was xylem.

Accepted Answer

Abundant sucrose during the summer in the stem would indicate the phloem.Please see section 21.6 for more information.

Question 15

Parasitic plants steal from other plants by making connections to the other plants' vascular tissue.

Accepted Answer

Parasitic plants take nutrients from other plants by contacting their xylem and/or phloem.Please see section 21.6 for more information.

Question 16

You are shown a flowering plant that,you are told,hosts ants that protect it.You are told that the ants walk along the veins in its leaves.To test whether this is accurate,you could prepare a model artificial leaf with veins that are

Accepted Answer

Please see section 21.4 and "Investigating Life" for more information.

Question 17

Mistletoe is an example of a parasitic plant.

Accepted Answer

Parasitic plants take nutrients from other plants.Please see section 21.6 for more information.

Question 18
