  3. Cacti and succulents

  4. Ferns and orchids
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The plants of the tundra are grasses, sedges, and mosses. These plants are able to survive in the cold climate and short growing season of the tundra.

Multiple choice

Which invasive species is known for its rapid growth and ability to outcompete native wetland plants?

  1. Phragmites australis

  2. Spartina anglica

  3. Typha latifolia

  4. Juncus effusus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phragmites australis, commonly known as common reed, is an invasive species that can rapidly colonize and dominate wetlands, displacing native plant species and altering ecosystem structure and function.

Multiple choice

What is the pioneer species in primary succession?

  1. Lichens

  2. Mosses

  3. Grasses

  4. Trees
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Lichens are the pioneer species in primary succession. They are able to survive in harsh conditions, such as bare rock or sand, and they help to create a more hospitable environment for other plants to grow.

Multiple choice

Which of the following is an example of homeosis?

  1. The development of wings in birds

  2. The formation of a flower from a shoot apical meristem

  3. The transformation of a leg into an antenna in some insects

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The development of wings in birds, the formation of a flower from a shoot apical meristem, and the transformation of a leg into an antenna in some insects are all examples of homeosis, demonstrating evolutionary changes in the identity of body parts.

Multiple choice

What is the pioneer species in primary succession?

  1. Grasses

  2. Shrubs

  3. Trees

  4. Lichens
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
