Summary Introduction
To review:
The hypothesis for the effects of acid rain on the tree’s primary growth. Further, make predictions about the impact of the acid rain on the height of tree trunks.
Introduction:
The growth of the plants in terms of shoot and root is referred to as the primary growth. The primary growth leads to the production of the vascular, ground, and dermal tissues.

An experiment is conducted to determine the effect of classical music on the
growth rate of marigolds (flowers). Two groups of plants are grown from seed in
identical soil types, exposed to identical light conditions, and given the same
nutrients. Group A is in a quiet atmosphere. The plants in group B provided with
the same atmosphere, except that classical music is played for twelve hours daily
in this area. The scientist measures the plants in both groups each day and
records the data. In experimental design, Group A is known as.*
experimental group
control group
non-experimental group
O quasi-experimental group

Group of answer choices The field capacity point is really low, causing water to seep through the soil quickly Both the wilting point and field capacity are really low, causing the soil to be immediately oversaturated The distance between field capacity and wilting point is extremely small, which makes the plants highly susceptible to changes in precipitation It has a high wilting point, a lot of rain has to fall before plants can access the waterarrow_forward
- How does acid rain lead to a reduction in the amount of plant nutrients available in soil? O Cation exchange leads to covalent bonding of nutrients on soil particles, making them unavailable to plants. O Nutrient cations (like K*, Ca++ etc) bind in place of protons released by soil particles, making the nutrients unavailable and the soil water more acidic. O Cations exchange places with anions during cation exchange, which confuses roots and turns LATS into HATS, after which the endodermis generates a caspian endothelium O During acid rain nutrients leach away after cation exchange takes placearrow_forwardThe small pores present of leaf’s surface are called: I.
