Plant Biology

Question 1

Bryophytes

Answer 1

Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface (e.g., their leaves).

Question 2

Vascular plants

Answer 2

The vascular plant contains xylem and phloem known as vascular tissues, for instance, conifers, flowering plants, and ferns.

The vascular plants include all the seed-containing plants, angiosperms (flowering plants), gymnosperms, and the pteridophytes (lycophytes, horsetails, and ferns).

Question 3

C4 photosynthesis

Answer 3

In C4 photosynthesis, where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in ‘bundle sheath’ cells around Rubisco. … PEP fixes carbon dioxide into a four-carbon molecule, called malate, that is transported to the deeper bundle sheath cells that contain Rubisco.

ex: maize, sugarcane, and sorghum

Question 4

Phreatophytes

Answer 4

Plants that suck up groundwater
