What is the function of meristems in trees?

• They store water for the tree

• They are zones of new cell growth

• They transport nutrients throughout the tree

• They protect the tree from pests

Which type of meristem is responsible for increasing the diameter of a tree?

• Apical meristem

• Lateral or secondary meristem

• Root meristem

• Leaf meristem

Why is it important to understand how water, sunlight, air, and elements interact in a tree?

• To improve the taste of tree fruits

• To know how these factors interact in a whole tree for better tree health care

• To increase the height of the tree only

• To make trees grow faster in all conditions

How do horizontally oriented meristems contribute to tree growth?

• By increasing the height of the tree

• By increasing the diameter of the tree

• By producing flowers

• By absorbing nutrients from the soil

Which of the following best describes the process of cell division in tree meristems?

• Cells divide randomly and do not specialize

• Cells divide, and only one of the two daughter cells differentiates to fulfill a specific function

• Cells divide and both daughter cells immediately become specialized

• Cells divide only once in a tree's lifetime

• Protecting the tree from injury

• Moderating tree temperature

Why is periderm important for a tree’s survival?

• It transports water and nutrients

• It is the main site of photosynthesis

• It acts as the first line of defense against pests, decay, and injury

• It stores carbohydrates for the tree

What is the primary function of buds on tree branches and twigs?

• To absorb water from the soil

• To allow for growth, expansion, and adjustment of tree crowns

• To anchor the tree in the ground

• To produce fruit directly

If a terminal bud is removed from a deciduous tree, what is the likely response of the lateral buds?

• They remain dormant indefinitely.

• They begin to grow and create new shoot development.

• They fall off the twig.

• They turn into flowers.
