Studdy Solution
2 Identify the term that describes the reproductive mechanisms in agriculture. In agriculture, many crops have been domesticated towards self-compatibility.
Many crops have been domesticated towards self-compatibility \text{Many crops have been domesticated towards } \boxed{\text{self-compatibility}}
The final filled-in passage is:
In angiosperms, male gametes are produced in the anthers\boxed{\text{anthers}}, while female gametes develop in the ovule's embryo sac\boxed{\text{embryo sac}}. Pollen grains carry a tube nucleus and a generative nucleus, each with a haploid\boxed{\text{haploid}} chromosome complement. Upon pollination\boxed{\text{pollination}}, the pollen germinates to form a tube that grows through the style\boxed{\text{style}} and in some species, the generative nucleus divides into two sperm nuclei. As the pollen tube enters the ovary through the ovule's micropyle\boxed{\text{micropyle}}, sperm nuclei are released into the embryo sac. The embryo sac, derived from the megaspore mother cells, undergoes mitosis\boxed{\text{mitosis}} and division, resulting in eight haploid nuclei. Crucial for seed formation are the egg cell and two polar nuclei. Fertilisation\boxed{\text{Fertilisation}} involves the fusion of one sperm nucleus with the egg cell, forming the diploid\boxed{\text{diploid}} zygote. Simultaneously, the other sperm nucleus fuses with the polar nuclei (or a central diploid nucleus), forming a triploid\boxed{\text{triploid}} nucleus that gives rise to the endosperm\boxed{\text{endosperm}}. Gymnosperms\boxed{\text{Gymnosperms}} generally release only one pollen sperm cell, whereas angiosperms\boxed{\text{angiosperms}} often display diverse mechanisms for pollination and fertilisation regulation. In agriculture, many crops have been domesticated towards self-compatibility\boxed{\text{self-compatibility}} and reproductive mechanisms are often modified to facilitate controlled cross-pollination.
