To answer the question "In plants, growth occurs ______ whereas in animals, it occurs ______," we can break down the information provided in the video transcript into a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding Growth in Plants:**
- In plants, growth occurs continuously throughout their life. This is primarily due to the presence of meristematic tissues, which are regions of undifferentiated cells capable of division.
- These meristematic areas allow for continuous cell division, enabling plants to grow indefinitely.

2. **Understanding Growth in Animals:**
- In contrast, growth in animals occurs only up to a certain age. After reaching maturity, the rate of cell division significantly decreases.
- In animals, cell division mainly occurs to replace damaged or dead cells, rather than to create new cells for growth.

3. **Filling in the Blanks:**
- Based on the above understanding, we can fill in the blanks:
- In plants, growth occurs **continuously**.
- In animals, it occurs **up to a certain age**.

### Final Answer:
In plants, growth occurs **continuously** whereas in animals, it occurs **up to a certain age**.
