Question

Define the following.

1. Mesophytes
2. Sporangia
3. Xerophytes
4. Pentamerous flowers

Answer 1

1. Mesophytes

1. Mesophytes are a group of terrestrial plants that can't adapt to wet or dry conditions.
2. In other words, they require a moderate amount of hot and humid climatic conditions.
3. Mesophyte plants live in soil that has an average dry-wet environment for overall growth.
4. They thrive in conditions where the concentration of water and temperature are not too high or too low.
5. Mesophytic plants have well-developed and differentiated vascular and mechanical tissues.

2. Sporangia

1. Sporangia are the reproductive structures found on the leaves of pteridophytes.
2. Sporangia can produce spores via mitosis, but in almost all land plants and many fungi, sporangia is the site of meiosis, producing genetically distinct haploid spores.

3. Xerophytes

1. Xerophytes are angiosperm terrestrial plants that can survive and thrive in desert habitats.
2. Any plant adapted to life in a dry or physiologically dry habitat (salt marsh, saline soil, or acid bog) through mechanisms that prevent water loss or store available water is referred to as a xerophyte.

4. Pentamerous flowers

1. These flowers are found in dicot plants.
2. These are flowers that contain all five floral parts.
3. Pentamerous flowers have flower parts arranged in groups of five.
4. Pentamerous flowers have five calyxes and five corollae.
5. For instance, Solanum, Chinarose, and so on.
