Which of the following were or soon became a challenge for survival of the first land plants? 1) sources of water 2) sperm transfer 3) desiccation 4) animal predation 5) competition with other plants for light

1 and 3

Explanation:

Sources of water: plants need water for certain cellular processes especially PHOTOSYNTHESIS. Otherwise, it Will not produce food and then die. So, first land plants need Sources of water.

Dessication: refers to drying up of plants tissues DUE to LACK of water. First land plant are most likely to suffer dessication.

Other options are NOT specific to first land plants

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
