Answer:
The cells of the visual cortex are neurons in the brain's visual system that respond to particular features of a stimulus.
Explanation:
These neurons respond to stimuli presented to both eyes. Simple cells receive innervation directly from thalamic cells and respond to light stimuli with defined orientation and with specific configuration and location in the visual field. Complex cells also respond to the orientation parameter.
These cells trigger action potentials when the visual stimulus appears within their receptive field.
Answer:The Cycad tree is the sporophyte.They have flagellated sperm.
Explanation:
During pollination, the contents of the megaspore divide to form many–celled gamateophyte called the endosperm and archegonium. There is a micropyle opening with a sticky fluid, which traps the wind-borne male gametophyte (microspores) which,at this time is made up of prothallus cell;an antheridial cell and a large tube cell. The trapped microspore is sucked into the archegonia chamber. Antherizoids are released, but only one penetrates each oospore and fuses with the female nucleus. The zygote is formed in the ovule and the later develops into seed.The diploid seed germinates into a new sporophyte plant and the life cycle begins again. Examples of cycad include Cycas circinalis ,Cycas celebrical and Cycas revoluta
