Angiosperm

Angisperms have adapted to life on land by allowin a more efficient way to become pollinated and fertilized. For example, the plant has evolved to have bigger plants and brighter colours for the plant so that the insects are attracted to the plant. The seed in angiosperms are dispersed usually by wind and water. Plans such as pollen ones are dispersed with wind as they are light and breeze. Fruit such as coconut are dispersed by water. This is true because when a coconut falls from the tree it may get swept with the water and land elsewhere to grow again. The purpose of the fruit is to protect the seed and make sure it becomes dispersed

Gymnosperms

Gymnosperms have adapted To different environments by a few things. They have a seed which allows for fertilization to become more successful because it is more protected. They have developed stronger vascular tissue for example evergreen trees. Trees such as the pine are thin which reduces transpiration which I water loss through the leafs. The difference between fertilization and pollination is that in pollination, the male sex part is the pollen which gets transferred to stigma. In fertilization, it is where the pollen or sperm meets the egg and they join to form a new life

Ferns

I found my ferns in an environment with moist soil and lots of sunlight. They are found in moist environments because for ideal conditions for reproduction where it needs the sperm to meet up with the egg. Ferns need water to uptake and give out to the whole plant through the xylem vessels in order for the plant to be healthy. It also needs water to transport spores. Mosses and ferns are different because ferns have a vascular system which involves xylem and phloem while moss have no xylem and phloem but have a sporphytic stage

Moss

I found the moss in a damp area which was the stream at the back of Sullivan heights on the ground and also on the bigger rocks. They are found near wet environments because they are small in size and have very thinness of tissue. They need a constant supply of water up through the rhizomes. They also have no cuticle to prevent water loss so they need the moist environment. They grow so low to the ground because it is a plant that needs the water to be up taken constantly. It thrives off the moistness

Pollination

Pollination is the movement of the male sex part which is the pollen from the stigma down the style and into the ovule to become fertilized and create a new flower. The differences between cross pollination and self pollination is that in self pollination the anthers transfer pollen froth e same flower onto the stigma. In cross pollination different animals such as bees transfer the sticky pollen onto a different flower of the same species. Self pollination is good because the flower does not rely on insects for transferring the pollen. Cross pollination is good because if the flowers anthers do not have much pollen on them they will not successfully fertilize the flower.

Dissecting Tulips

Today in class we dissected  flowers. 

Below are a few of the parts that make up the flower

Monocot and dicots - roots

This is a picture of a Dicot in a root. I know that this is a Dicot because of the arrangement of the vascular bundle which is on the outside against the epidermis. This is different to the monocot root which has the vascular bundle in the centre coming through instead of on the outside
