An amniotic egg is the egg of an amniote, a clade of tetrapod vertebrates that includes mammals, birds and reptiles. These eggs are either laid on dry land (like a bird’s nest) or stay within the mother after being fertilized (like a human). Above we see the eggs of chickens, a type of bird amniote.

Dispersing ones child seeds is always a challenge for a stationary plant. One way to overcome this is to develop adaptions to hijack animal’s freedom of movement as this Huckleberry bush has done. The Huckleberry grows berries around its seeds, which are just the right size for birds to snack on. The birds then fly to another location while digesting the berries and poop out the indigestible seeds at the new site. In this way the birds and the bushes have developed a symbiotic relationship where the bushes feed the birds and the birds spread the bushes.

Pollen is to a plant as sperm is to a mammal. Pollen is made up of microscopic grains that each carry a male gamete and are capable of fertilizing a plant’s female ovule. It is usually a yellow or orangish powder and is produced and released from a flower’s male cone, and relies on the wind and contact with insects for transport. Above we can see several flowers containing yellow pollen towards their centers.

A Pollinator is a bug or animal that (willingly or not) moves pollen around a flower and between plants. This movement of pollen, or pollination, allows many plants to reproduce, flower, and bear fruit. Bees, like the one pictured in the flower above, are the best pollinators as they source their food from inside flowers and so spend a lot of time brushing up against them and pollen. Butterflies and hummingbirds also make great pollinators for the same reasons.

Fleshy fruits with seeds are, well, fruits with inner seeds surrounded by “flesh.” These peaches, for example, have a central pit with a seed surrounded by layers of fleshy, wet fruit. Tasty too.
List #50
A Spore is usually a small single-celled reproductive unit capable of growing into an adult individual independently, similar to a seed. In this photo we see clumps of orange fern spores on the underside of a sword fern. For scale the blue footed booby is about 1.5 inches tall.
List #100
Seed dispersal is the means by which a parent plant spreads its child seeds about the environment. We can see here this dandelion plant has developed a way to disperse its seeds using the wind. The white tuft contains several seeds attached to a feather-like head, which pulls the seed up and away if the wind blows hard enough.
