Why do conifers need 2 types of cones to form seeds?
because some of the cones are male cones, and some of the cones are female cones. the male cones produce the pollen and sperm, and the female seeds contain the seeds.
Rods and cones are?
Rods and cones are photoreceptors in the eye that allow people to see. Rods allow people to see colors, while cones allow people to see in low light, and in great detail.
Why are traffic cones cone shaped?
Traffic cones are orange because it makes them stick out more, making them easier to notice.
Cones are sensitive to what light in biology?
Cones are sensitive to Red light (L cones, 64%) Green light (M cones, 32%) and Blue light (S cones, 2%)
What are the rods and cones and what will each one do?
Rods and cones are things in your eye that help you to see black and white. Rods are more sensitive than cones. They're what makes optical illusions possible for our eyes along with perception. Rods are sensitive to only the brigtness of the light, and allow us to see in black and white. Cones provide color vision.

Why is a light sensor better than your eyes?
The retina contains two types of photoreceptor's, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to colour.
Why are some animals colour-blind?
They have less cones in their eyes. Humans have cones and rods. The cones are for color and rods are for light. Cats have a ton of rods so that is why they can see in the dark well and humans can't. The more rods you have, the better you can see at night or in the dark. Animals have a lot more rods because that is more beneficial to them than seeing colors.
What does zane dosset have that other people do not have?

Compare rods and cones?

How often do fir trees produce cones?
The male cones are formed in the spring near the branch tips and are short-lived. Female cones are produced the following summer and are not fertilized until the spring of the next year. A fir tree may be 8-10 years old before it starts to produce cones. Some years it will have far more cones than others. This is in response to environmental conditions such as weather, a stressed tree makes more of an effort to make sure it reproduces before dying.

What is in the back of the eye holding 3 million cones on a billion rods?
The retina contains the rods and cones. There are more rods than cones but is is more like 120 million rods to 5 million cones. Both are special cells that are photoreceptors. This means that they are sensitive to light. The cones are best for color vision but the rods are for low light. That is one reason why you don't see color in low light.
What types of cones are there?
Ice cream cones, mathematical cones, frustums, traffic cones, pine cones...
How are pollen cones and seed cones are different?
Seed cones (female cones) are much larger than pollen cones (male cones).
Which animals have more rods than cones in their eyes?
Nocturnal animals in general have many rods than cones in their eyes. Rods are used more for dim light and seeing motion.
What colors does a tetrachromat see?
I don't recall exactly, but I believe they see the same colors most people do, except much more vividly. That is, we have "cones" in our eyes that see Red Green and Blue, and while they don't have other colored cones, Tetrachromats' have EXTRAcones.
