Plant growth is generally indeterminate, not determinate. This means that plants typically continue to grow as long as they live, unlike animals which have a determinate growth and stop growing after reaching a certain age or size. The meristematic tissues in plants (such as the apical meristem, lateral meristem etc.) allow for continuous growth and production of new cells. This is a key characteristic of plants. So, the statement that plant growth is generally determinate is incorrect.

Plant Growth and Development
Plant growth and development are complex processes that involve various phases and cellular events. Let's analyze each statement to identify the correct answer.
Statement a: Phase of cell elongation of plant cells is characterized by increased vacuolation.
This statement is correct. During the cell elongation phase, plant cells undergo rapid expansion, and one of the mechanisms that contribute to this expansion is vacuolation. The vacuoles within the plant cells increase in size, causing the cells to elongate.
Statement b: Cells in the meristematic phase of growth exhibit abundant plasmodesmatal connections.
This statement is correct. The meristematic phase of growth is characterized by the division and differentiation of cells. During this phase, cells are actively dividing, and they maintain abundant plasmodesmatal connections. Plasmodesmata are channels that allow the movement of substances between plant cells, facilitating communication and coordination during growth and development.
Statement c: Plant growth is generally determinate.
This statement is incorrect. Plant growth can be categorized into two types: determinate and indeterminate. Determinate growth refers to the growth pattern where the final size of the plant or its organs is predetermined. Once the plant reaches its mature size, further growth stops. In contrast, indeterminate growth refers to continuous growth throughout the plant's life. This type of growth is observed in plants with meristematic tissues, such as shoot and root apical meristems.
Statement d: Plant growth is measurable.
This statement is correct. Plant growth can be measured using various parameters such as height, biomass, leaf area, or number of flowers. These measurements help in understanding the growth patterns and responses of plants to different environmental factors.
Therefore, the correct answer is option 'C' - Plant growth is generally determinate.
