Cycas is a group of plants that belong to the division Cycadophyta. They are commonly known as cycads and are considered to be living fossils because they have been around for millions of years. Let's analyze the given options to determine which statement is incorrect about cycas.
a) It has unbranched stem:
Cycas plants have a woody, unbranched stem called a trunk. The trunk is covered with persistent leaf bases, giving it a rough texture. This statement is correct.
b) It possesses pinnately compound leaves:
Cycas plants have large, compound leaves that are pinnately compound, meaning the leaflets are arranged along a central axis. The leaflets are leathery and have parallel venation. This statement is correct.
c) It is a dioecious plant:
Dioecious plants have separate male and female reproductive structures on different plants. Cycas plants are indeed dioecious, with male and female cones produced on separate plants. The male cones produce pollen, while the female cones produce seeds. This statement is correct.
d) It is a non-archegoniate plant:
The term "archegoniate" refers to plants that possess archegonia, which are structures that produce and house the eggs. Cycas plants do produce archegonia and are therefore archegoniate. This statement is incorrect, making option 'D' the correct answer.
In conclusion, the incorrect statement about cycas is that it is a non-archegoniate plant. Cycas plants do possess archegonia and are therefore archegoniate.
