Front

What connects the sieve-tube elements in phloem?

Back

A sieve plate connects the sieve-tube elements.

Front

What are the main components of phloem in angiosperms?

Back

The phloem of angiosperms is primarily composed of sieve-tube members.

Front

Define angiosperm.

Back

Angiosperms are vascular plants that flower and produce fruits containing seeds.

Front

What is the role of vessel elements in vascular plants?

Back

Vessel elements are dead at maturity and do not require helper cells.

Front

How can leaves be classified based on their structure?

Back

Leaves can be classified as simple, serrate, and netted pinnate.

Front

What is the function of sieve-tube members in plants?

Back

Sieve-tube members are responsible for the transport of nutrients and sugars in the phloem.

Front

What distinguishes angiosperms from other plant groups?

Back

Angiosperms are distinguished by their ability to produce flowers and fruits.

Front

What is a sieve plate and its function?

Back

A sieve plate is a porous structure that allows for the flow of sap between sieve-tube elements.

Front

What are the characteristics of vascular plants?

Back

Vascular plants have specialized tissues (xylem and phloem) for the transport of water, nutrients, and food.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from roots to leaves, while phloem transports sugars and nutrients throughout the plant.
