SI Leader Justin Remmell Course Biology 242 01 Instructor Dr Hoffmann Spring 14 Chapter 38 Plant Reproduction and Development Seeds Seeds come from the The seed coat is formed from the of the ovule Nutrition is stored in the seeds The is the part of the stem of an embryo plant beneath the stalks of the cotyledons and directly above the root The is the part of the plant embryo that develops into the primary root also is the first part of the seed to emerge during germination The is the place above where the cotyledons are attached The absorb nutrients from the endosperm and transfer them to the rest of the embryo when the seed germinates Two protective sheaths enclose the embryo the which covers the young shoot and the which covers the young root A garden bean has a seed It consists of a seed coat and embryo with Corn a seed consists of a seed coat endosperm and embryo with Seed Structure cotyledons and endosperm cotyledon Eudicot Seed Germination germination When a seed matures it dries and becomes until conditions are better for When the environment becomes advantageous to the seed the seed will go through the uptake of water The is the first to emerge The then emerges and pulled seed out after it Monocot seed germination Much like a eudicot seed it leaves dormancy through the uptake of in imbibition and the emerges first The pushes upward through the soil and into the air Fruits Mature Walls of the ovary become the the thickened wall of the fruit are fruits that are derived from a single carpel or several fused carpals are fruits that develop from many separate carpels of one flower are fruits that develop from many carpals of the many flowers that form an inflorescence A is a fruit that develops largely from tissues other than the ovary Fruits can be like grains beans and nuts or they can be like oranges and grapes Fruit and seed dispersal o like the coconut o with winged seeds or fruits
